摘要：

Irradiation of O-alk-3-enylsalycylates 1 at lambda = 254 nm yields tricyclic compounds 2 containing a cyclobutene moiety. The efficiency of the intramolecular photocycloaddition increased and the reaction mixture was greatly simplified when the reaction was carried out in methanol in the presence of a catalytic amount of acid.
